WebView2
The WebView2 control hosts the Microsoft Edge browser engine inside a twinBASIC form — navigate to web pages, run local web apps, exchange messages and method calls with JavaScript, intercept HTTP traffic, and print pages to PDF.
These tutorials demonstrate the most common patterns:
- Getting started – adding the package references and dropping a control onto a form.
- Customize the UserDataFolder – relocating the runtime’s working folder for hosted scenarios (Office add-ins, kiosk installs).
- Re-entrancy – what the control’s deferred-event machinery does for you, and the one place you still have to think about it.
- Building a browser shell – address bar, back / forward / reload, zoom, PDF export — turning the control into a working browser.
- Hosting local web assets – serve HTML / JS / CSS from a project resource folder, without an HTTP server.
- JavaScript interop – the three bridges between BASIC and the page: host objects, messages, and scripted calls.
- Driving Monaco from twinBASIC – a case study combining everything above: embed Microsoft’s Monaco editor next to a live HTML preview pane.
The complete sample code for the last four tutorials ships as Sample 0 — WebView2 Examples in the New-Project dialog.
